Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. [ 1 ] [ 2 ] [ 3 ] Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartographic representations.

The fourth quadrant also has Frequently Asked Questions (FAQs) and their answers to clarify common misconceptions among students. [ 10 ] The University Grants Commission (UGC) considers that universities should play a key role in publicizing and popularizing SWAYAM courses among their learners and the university, enabling them to gain from ...
Course Hero was founded by Andrew Grauer at Cornell University in 2006 for college students to share lectures, class notes, exams and assignments. [ 4 ] In November 2014, the company raised $15 million in Series A Funding, with investors that included GSV Capital and IDG Capital.
For example, at a radius of 6600 km (about 200 km above Earth's surface) J 3 /(J 2 r) is about 0.002; i.e., the correction to the "J 2 force" from the "J 3 term" is in the order of 2 permille. The negative value of J 3 implies that for a point mass in Earth's equatorial plane the gravitational force is tilted slightly towards the south due to ...
Multiple choice questions lend themselves to the development of objective assessment items, but without author training, questions can be subjective in nature. Because this style of test does not require a teacher to interpret answers, test-takers are graded purely on their selections, creating a lower likelihood of teacher bias in the results. [8]
G299.2-2.9 is a supernova remnant in the Milky Way, 16,000 light years from Earth. [2] It is the remains of a Type Ia supernova . [ 3 ] The observed radius of the remnant shell translates to approximately 4,500 years of expansion, [ 4 ] making it one of the oldest observed Type Ia supernova remnants.
A "true circumnavigation" of Earth is defined, in order to account for the shape of Earth, to be about 2.5 times as long, including a crossing of the equator, at about 40,000 km (25,000 mi). [24] On the flat Earth model, the ratios would require the Antarctic Circle to be 2.5 times the length of the circumnavigation, or 2.5 × 2.5 = 6.25 times ...
